i have a small doubt,plz validate the following statements

01 A PIC X(05).
01 A-NUM REDEFINES A PIC 9(05).

IF A-NUM NUMERIC
PERFORM X-PARA
ELSE
PERFORM Y-PARA.

PLZ validate the above statements,whether numeric can be used here or not???if not when numeric can be used???
explain with some examples..

thanks
katakam.

Just say IF A NUMERIC. Then you know if A-NUM is valid.

what owen said is correct.

we check the filed which can store char or num ie. alphanumeric filed. so we check whether the numeric data present in the field.

what is the point in checking filed already defined as numeric.
